Nope. Thanks for the info!

Jack,
Save yourself some time and add ~50% hot glue to the wax. It raises the
melting point without reducing the ISP a ton. This helps the regression
rate stabilize over straight waxy. And, doing a nitrous/wax hybrid you
don't care about ISP, right?

Hello!
So I've been occasionally popping into here to ask questions about a
hybrid nitrous oxide + paraffin mixed with carbon black engine. I've gotten
a good idea of what I want to do with the engine, but now since I finally
have a job and some disposable income I can start buying things and
actually make a schematic of a design.
So, how to math?
I know NASA had some site that has a very in depth calculator for some
sort of either ISP / thrust / fuel or something, but it's broken as far as
I can tell and I don't know of any alternatives. I think it would be better
to do more math and get a more specific design set out as i'm not going to
be building this for a while anyways, as I still lack access to a lathe and
mill due to coronavirus.
In the meantime, there was an email about a dirt simple DIY nitrous
rocket that somebody had sent to me, and it looks like a fun project to
just get a toe in the water when it comes to rocketry so I know how to deal
with engines and what's safe and just get a feel for them, so i'm wondering
what are some best practices for nitrous oxide handling, and what i would
need for a simple plumbing system that would run a tiny ~4inch rocket. If
possible I would also love a design that mimics what I would require for my
hypothetical rocket so far, that being the nitrous. If anyone has any good
resources, that would be absolutely wonderful. An overkill setup would
ideally be perfect as the best thing I can think of is a very "boring"
static fire.
I'm just getting into physics and calculus now, but I don't particularly
think that the equations would be too complicated, and if they were, I
think I can work through them or ask one of my teachers for help.
Thanks so much for all the help, ya'll been a great help.
